- Sublimation don't change the molecule; solid iodine or sublimated iodine are iodine. - Slaking of lime transform the calcium oxide in calcium hydroxide. A chemical change occur.
Sublimation is the physical change of a solid to a gas skipping the step of becoming a liquid. This is a physical change because you haven't changed the chemical nature of the substance. Think of when you take ice out of the freezer and you see "smoke" coming off of it. That is sublimation. The rapid change in temp caused the solid ice to skip its liquid stage and go straight to its gaseous stage
Iodine sublimes into a purple gas without passing through a liquid phase. This is a change in physical state, which is a physical change.
Deposition examples: gaseous iodine, and the water in snow clouds.
Yes.
physical change
Iodine melting is a physical change.
Chemical Change
Chemical- Iodine reacts with the starch of the bread.
It is a physical change (sublimation).
It is a Physical Process because, there is no chemical change in the Iodine. The only change that occurs is the change from solid to vapor state of the Iodine.
No, sublimation is a physical change.
if u heated them then its a physical change if u chucked another chemical on them its a chemical change if u did both then its a change of clothes
Chemical Taylor:)
Its a physical change as there is no reaction.
This is a physical process.
Purple vapour appearing = physical
